im lost evaluate 30 divided by 5*3-2 all over/2-2divided by 3

You 'll have to clarify that. Do you mean:

30 / (5*3-2)/ (2-2/3) ?

no Ill try to write it out thirty divided by 5 times 3 minus 2 all of this is over 2 minus 2 divided by three any better?

I'm sorry, but I'm still not clear.

Maybe it's

((30/5) *( 3-2)) /(2-2/3)) ?

That would be

(6 * 1) / (4/3) = 6 * 3 / 4 = 4.5

30 divided by 5 multiply by 3 subtract 2 then there is a line and under the is 2minus2divided by 3 any better?

    Diana,
    Whenever you are posting a fraction where the numerator and denominator are separated by a line, you will need to include ALL parentheses originally present in the expression AND put parentheses around the numerator and the same for the denominator, even the additional parenetheses are not present in the expression. This last step is necessary because we do not see how far the horizontal line goes in your post.

    Can you repost the expressions? Your last description is a little clearer, but since there are 3 divisions involved, and a multiplication follows immediately the first division, it is not clear what denominator goes with the first division.

    There are no parenetheses

  • Math -

    I understand that there are no parentheses on the numberator and denominator. If you have a line in the middle, the parentheses are implied. Since we do NOT see the middle line from you post, you will NEED TO ADD the implied parenthesis for us to interpret the question correctly.

    "im lost evaluate 30 divided by 5*3-2 all over/2-2divided by 3"
    I am lost also as to what you would like to evaluate because the description can mean many things.

    The priority of operations is as follows:
    1. parentheses
    2. exponents
    3. multiplication and division, from left to right
    4. addition and subtraction, from left to right.

    If I interpret your expression verbatim, I get:
    "30 divided by 5*3-2 all over/2-2divided by 3"
    (30/5*3-2)/(2-2/3)
    So according to the rules, we evaluat eas follows:
    (30/5*3-2)/(2-2/3)
    =(6*3-2)/(2-2/3)
    =(18-2)/(2-2/3)
    = 16/(2-2/3)
    = 16/(2-2/3)
    = 16/(4/3)
    = 16*(3/4)
    = 12

    If there was another line between 30 and (5*3), the answer would be completely different, because the expression would be (30/(5*3)-2)/(2-2/3)


    We are not sure if this is what you want. We are trying to have you confirm the correct transcription of the question, which is vital to solving a math problem.
